"LAMP-IGNITING Device.

To cllfwlwm t may lConcern Be itiknown that L'JnnsoN ci tizen kof the United States, residing at Pleasant Hill, in the county 2of Miami and State of vOhio, have invented certain new and useful Improvements in Lamp-Igniting Devices; and I do hereby declare the follow-- mg togbea full, clear, and exact Ldescription of the invention, such as willfenable others skilledin theart `-to which it appertainsto makeand 'use the same. y

The vinvention -relatesto lamp 'igniting devices. 1 -f Theobjiect of the present invention is to improve the construction aof igniting devices for lamps and toxprovider a simple, practical and comparatively inexpensive igniting device adapted to be readily applied to a lamp burner-and capable loffenabling the sametov be lighted withouty the use of matches `and adapted also to 'extinguish the lighting means and clean the device so that the samev will be inl properfcondition for a succeeding operation. .y i

With these andA other objects inxview the invention `consists, in the construction and novel combination and arrangementof parts hereinafter fully described, illustrated in the a ccom-panying drawings f and pointed tout in the claims hereto appended, it being understoodthat various changes in the form, proportion and min-or details of' construction may be resorted to without -fdeparting from the :spirit or sacrificing any of 'the :advantages of the invention. i, i f

responding partsin the several figures of the drawing. f

y In the .accompanying drawing in which is illustrated the preferred embodiment of the invention, the igniting device comprises in its construction, a sparking device and a wick tube preferably consisting of a small tube extending through the lower portion of burner `below the cap 2 thereof and soldered or otherwise secured te the lamp burner 3 which may be of any desired' con,

struction and which is provided with the usual wick `tube 4. The wick tube l of the ignitingdevice is connected at its lower end with a reservoir kor receptacle 5 preferably in the form of a cylindrical tank having a v threaded `closure plug 6 at the top to enablev itto be readily filled as required. The ig- The flange 7 isllocated a short distance below vthe upper extremity of the pipe or tube l which contains the wick 11 of the igniting device and which terminates short of the upper end of the main wick tube 4C of the burner,- the flame from the igniting 'device being 1directed to the 'wick of ythe lamp by an upwardly tapered hood 11 provided at the top with lan vopening and suitably mounted `on the main wick tube l or otherwise supported in kposition as shown with its `open upper end at the top of the said main wick tube. When the i'rgniting device is lighted the name therefrom will be causedto ignite and light the main wick ofthe burner.

The sparking device comprises ythe said wheel 10 which is mounted on a shaft 12 journalfed yin suitable hearings of the burner.

vThe bearings are preferably formed `by a tube 13 and the shaft is provided at its outer c end with a hand wheel or disk 11i adapted to be turned by the operation or by rotating the wheel 10 to cause the periphery thereof which is provided with projections or spurs 15 to engage a piece of sparking material 16 to coact with the wheel 10 for producing duce a spark and the wick of the igniting` device is lighted thereby. In order to facilitate the production of a spark7 the shaft which carries the rotary wheel or movabley element 10 is provided with a lug or projection 17 which is engaged by a substantially at spring 1S mountedl on the tube 13 and adapted to retard the rotation of the shaft 12 while the spring engages the lug, so that a relatively strong turn is necessary to rotate the shaft, which will cause the lug to snap past the spring and thereby produce a relatively quick movement of the projections of the whe-el 10 over the sparking material and gives a good spark. The spring 18 engaging the lug 17 on the shaft 12 prevents accidental displacement of the cap 23 (which will be more fully hereinafter described) od of the supplemental tube 11. The flint or coacting sparking element is maintained in contact with the Wheel by a coiled spring 19 arranged ina tube or holder y20 disposed vertically and provided at its lower end with a threaded perforation 21 which receives a screw 22 adapted to be adjusted for controlling the tension of the spring to maintain the.

said relatively liXed sparking element in contact with the sparking wheel. The screw 22 is adapted to be adjusted from time'toy time as the flint becomes worn or used.

The'rotary sparking wheel carries ak cap 23 constructed of suitable metal and provided with a flange 24 located at one of the side faces of the wheel 10 and rigidly connected therewith preferably by being vfixed to theshaft 12 but it may be mounted in po` sition in any other desired manner. The eX- tinguishing cap which is adapted to be carried to and from the upper end of the wick tube 1 lits over the same and against the,

flange thereof and extinguishes the light of the igniting device after the lamp has been lighted. The cap is provided with an interior packing 26 of asbestos or other suitable material. The cap 23 is carried to and from the wick tube by the partial rotary movement of the shaft 12 and the rotation ofl the shaft to the right produces a spark and ignites the wick of the tube 1 and the rotation of the shaft to the left returns the cap to the tube 1 and at the same time moves the wheel 10 over the sparking lmaterial in a n radii of the wheel so as to engage the spark- 'ing material and dig into the same when the wheel is rotated to the right and to pass over the sparking material without digging into the same when the wheel is rotated to the left. rlhe cap forms an air tight closure for the wick 1 so that the contents of the tank will not be permitted to evaporate when the igniting device is not in use.

What is claimed is 1. The combination with a lamp burner, of a supplemental wick tube, and a sparking device including a shaft, a rotary sparking element mounted on the shaft, a relatively fixedl coacting sparking element bearing against the periphery of the rotary sparking elements, a cap secured on the shaft and arranged to be placed on'and removed from the supplemental wick tube by the rotation of the shaft, a projection carried by the shaft and yieldable means arranged in the path of the projection for retarding the rotation of the shaft and prevents accidental movement thereof, so that the cap is prevented from being accidentally displaced from said supplemental wick tube.

2. The ycombination with a lamp burner, of'a supplemental wick tube, and a sparking device including a shaft, a rotary sparking element mounted on the shaft, a cap carried by the rotary sparking element and arranged to be placed on and removed from the supplemental wick tube by the rotation of said element, a 'relatively fixed sparking element arranged to be engaged by the rotary sparking element, a tube forming a bearing for the shaft, a projection carried by the shaft, a spring mounted on the tube and extending into the path of the projection for retarding the 'rotation of the shaft and preventing accidental movement thereof, so that the cap is prevented from being accidentally displaced from said supplemental tube.
